The International Society of Genetic Genealogy (ISOGG) was founded in 2005 by DNA project administrators who shared a common vision: the promotion and education of genetic genealogy. The society's stated mission is "to advocate for and educate about the use of genetics as a tool for genealogical research, and promote a supportive network for genetic genealogists". The society is a non-commercial non-profit organization, and there are no membership fees/dues. ISOGG publishes an occasional newsletter. As of January 2013 ISOGG has over 8,000 members from 69 countries.

The ISOGG Wiki appears to be an extraordinarily valuable website for those investigating the DNA testing as a tool to extend their genealogical research. The website is current and constantly changing with new material and corrections to existing articles. Here is a list of some sample articles:
